Precast hollow slab forming machine operating skills the prefabricated plate exposure do not are on firm ground, prefabricated machine idle for a long time, in order to avoid vibration, dynamic - jump no attaint parts, prefabricated machine operation, should relax the cable to maintain a certain degree of, in order to avoid deformation, stretching, resulting in floor plate shock and motor line package damage, prefabricated plate on mobile. Use of prefabricated plate, the worker labor intensity from lower, high speed, compact texture, plate type and tidy, size accurate, site usage and high turnover is fast, is ideal to replace the rest of the production method of prefabricated equipment research and development design, the hopper of the crank to fixed with peg, avoid people into the cleaning barrel, body hit make the hopper, the extrusion, concrete circular orifice plate is widely used in industrial and agricultural construction, due to manufacturing is quite convenient, particularly strong economic practicability, got the applicability of the market is at present the commonly used on market becomes hollow floor.
